Description

Technical Field

[0001] This utility model belongs to the field of pellet milling technology, specifically relating to a functional food pellet milling machine. Background Technology

[0002] A functional food granulator is a mechanical device that uses physical or chemical methods to produce granular products from functional raw materials. It primarily involves mixing raw materials with a binder to form a moist, soft material, which is then granulated through extrusion, rotation, or cutting. After drying, the finished granules are obtained. Functional food granulators not only granulate functional foods, improving the dissolution rate and solubility of raw materials for easier absorption, but also reduce the volume of raw materials, facilitating packaging and storage. Functional food granulators are widely used in health foods, traditional Chinese medicine granules, nutritional supplements, and special dietary foods.

[0003] Chinese Patent Publication No. CN219879847U discloses a functional food pellet mill, comprising a table, a circular frame fixedly mounted on the top of the table, a motor fixedly mounted on the top of the circular frame, a three-bladed turntable fixedly mounted on the power output shaft of the motor, a gear two penetrating the inner wall of the three-bladed turntable, and gear one meshing with the top outer edge of gear two. This functional food pellet mill, through the combined use of the motor and the three-bladed turntable, and controlled by a controller, causes the motor to rotate, thereby rotating the three-bladed turntable. The rotation of the three-bladed turntable causes gear two to mesh with the outer edge of gear one, and further causes the bottom outer edge of gear two to mesh with gear three. This, in turn, causes a strip-shaped block to move in a circular motion around gear two, thus stirring the food ingredients and making them more evenly mixed.

[0004] In practical use, this utility model typically uses processes such as extrusion or cutting to transform raw materials into granules. However, after the granulation process is completed, the granules in existing functional food granulation machines often fall directly into the collection device. Due to the cooling and molding structure, functional food granules are prone to surface adhesion or structural deformation during free fall due to factors such as material characteristics, environmental humidity, and impact. This not only affects the integrity of the product's appearance but may also lead to a decrease in the uniformity of granule size, thereby restricting the actual application efficiency of the equipment in the field of functional food production and the stability of product quality.

This provides structural assurance for the density uniformity and quality stability of functional food granules. Attached Figure Description

[0025] Please see Figure 1-6 This utility model provides a functional food pelletizing machine, comprising: 1. Granulator body and 2. The forming plate 3 is set inside the pellet mill body 1. The drive shaft 2 is located inside the pellet mill body 1 and its bottom end passes through the forming plate 3. The upper end of the drive shaft 2 passes through the pellet mill body 1 and extends to the outside. The upper end of the forming plate 3 is provided with an extrusion block 4 that is adapted to the inner wall of the pellet mill body 1. Multiple cutting blades 5 are all located on the outside of the drive shaft 2. Multiple cutting blades 5 are all abutted against the bottom of the forming plate 3. The forming plate 3 is provided with multiple forming holes. The inner wall of the pellet mill body 1 is provided with a transmission groove. Multiple guide plates 6 are all located at the bottom of the drive shaft 2. A feed inlet 7 is provided on one side of the upper end of the pellet mill body 1.

[0026] Specifically, such as Figure 2 As shown, a fixed plate 23 is provided at the upper end of the main body 1 of the pellet mill. Multiple positioning sleeves 24 are rotatably connected to the bottom end of the fixed plate 23. Multiple stirring blades 25 are provided on the outer side of the drive shaft 2 and the multiple positioning sleeves 24. The multiple stirring blades 25 are arranged in an alternating manner.

The outer side of each positioning shaft 26 is provided with a spiral groove. The upper ends of the multiple positioning shafts 26 are respectively located inside the multiple positioning sleeves 24. One side of the inner wall of each of the multiple positioning sleeves 24 is provided with a positioning pin 27 that is adapted to the spiral groove. One end of each positioning pin 27 is located in the multiple spiral grooves and is slidably connected to the side wall of the spiral groove.

[0028] Through its design, when the extrusion block 4 drives multiple positioning shafts 26 to move up and down, the multiple positioning shafts 26 will rotate through the outer spiral groove and the positioning pins 27 inside the multiple positioning sleeves 24, thereby enabling multiple stirring blades 25 to rotate synchronously, fully mixing and stirring the functional food, ensuring the uniformity of the mixture, and improving the quality of functional food granulation.

[0029] See Figure 1-6 When using a pellet mill to produce functional food pellets, the functional food raw materials are first added into the pellet mill body 1 through the feed inlet 7. Then, the drive motor 20 is started. The output end of the drive motor 20 will drive the drive shaft 2 to rotate. The drive shaft 2 will drive the mounting pin 15 and the extrusion block 4 to move up and down through the outer spiral reciprocating groove. The extrusion block 4 will drive multiple positioning shafts 26 to move. With the spiral grooves on the outer side of the multiple positioning shafts 26 and the positioning pins 27 in the multiple positioning sleeves 24, the multiple positioning sleeves 24 can rotate, thereby allowing multiple stirring blades 25 to rotate and fully mix the functional food. During the granulation process of functional food, the baffle ring 17 needs to be moved upward to open multiple feed ports 16. The functional food in the main body 1 of the granulator will enter the transmission trough through the multiple feed ports 16 located at the top. When the extrusion block 4 moves upward, the functional food in the transmission trough will move to the forming plate 3 through the multiple feed ports 16 at the bottom. When the extrusion block 4 moves downward, the functional food will be extruded through multiple forming holes. When the drive shaft 2 rotates, it will drive multiple cutting blades 5 to rotate, thereby cutting the extruded functional food to form granules. When granular functional food needs to be cooled and shaped, the air pump 12 needs to be started. The air pump 12 draws air from the granulator body 1 through the air supply pipe 11 and the exhaust port 9, so that the powdered functional food raw materials can be sucked onto the filter screen 10 to prevent them from drifting outward. The filtered air will enter the air supply channel in the drive shaft 2, and then enter the rectangular grooves in the multiple guide plates 6, and be discharged through multiple exhaust holes 13. It can evenly contact the cut functional food particles, thereby effectively cooling and shaping them, preventing them from sticking or deforming, and ensuring the regularity and integrity of the product appearance.
